Hello - a few vendors have the vpi stuff 10% off and I was wondering from those who have the ads if it was a worthwhile purchase. What audible changes did you experience and is the ads a better purchase than the ring? (I am comparing these 2 because both are the same amount of money)Thanks

The ADS improves rotational accuracy if you have “dirty” power. The periphery ring also improves rotational accuracy, but corrects for mechanical causes of inconsistency. In addition, the ring flattens and improves the sound of warped records and, in my experience, somewhat improves sound quality in general. All VPI tables have inherently accurate rotational speed. If you have clean power, the ADS won’t do too much for you. If you don’t play warped records and your platter doesn’t vibrate from internal or external causes, the ring may improve sound quality a bit, but probably not materially. However, the periphery ring looks cool. Rich

Voltage is not as relevant in an AC motor as it is in a dc motor. But frecuency is fundamental, the googd part is that frecuency is usualy more stable tan voltaje in the grid.

You could buy a cheap voltage/frecuency meter (us$10-20) to check the quality of your power, take notice when the most heavy usage occurs and the hours you normaly use your system, think is worth doing compared to the ADS price.

ADS Will also change between 33/45 so no more moving the pelt in the pulley, don´t think that worth US$1000
